Application filed December 26, 1896. Serial No. 617,041. (No model.)

To all who/vt it may concern:

Be it known that I, ROBERT DAWEs, a citi- Zen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Spinning or Twisting and finding Machines, of which the fol'loWingis a specification. Y

My invention consists of certain improvements in the spinning or twisting and Windro ing machine for which I have obtained Letters Patent No. 481,787, dated August 30, 1892, and No. 552,217, dated February 4,1896, one of the objects of my present invention being to provide simple and etlicient means for guiding and retaining the rope or cord in its course from the draft-oapstans to the spool upon which it is being wound, and a further object being to prevent the access of fine dirt, lint, or other foreign matters to the bearing of the ring in the annular traverse-frame. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in Which- Figure 1 is a view of suflicient of a spinning or twisting machine to illustrate my present invention. Fig. 2 is an end view of part of the machine. Fig. 3 is a sectional view of part of the mechanism shown in Fig. 1, but with some of the devices in a difterent'position fromrthat illustrated in said Fig. 1. Fig. 4 is a transverse section on the line 0c x, Fig.

1; and Figs. 5 to 9, inclusive, are detached views of parts of the machine, Figs. 5 to 8, inclusive, being` on an enlarged scale.

So far as the general construction and operation of the spinning and Winding machine is concerned it is similar to that set forth in my former patents, and hence need not be specifically set forth herein further than to say that 1 represents the :dier-spindle; 2, the longitudinal bars of the Hier; 3, the spindle which supports the spool upon which the rope or cord is to# be Wound, and 4 the annular traverse-frame which surrounds the flier and is moved to and fro throughout the length of the spool by suitable mechanism. This annular traverse-frame is grooved or recessed vfor the reception. of a ring 5, having projectingears 6, to which are bolted corresponding ears upon segmental shoes 7 and 8, (see Figs. 5

and 6,) these shoes embracing the longitudinal bars 2 of the flier and being free to move longitudinally thereon.

Secured to eachvof the longitudinal bars of the flier, near one end of the same and in line with the draft-capstans 9, is a split ring 10, Which is clamped upon the longitudinal bar of the flier by means of a transverse bolt 11, said ring having a guide-block 12, With inner curved or rounded face, as shown in Fig. 1. 6o A similar curved or rounded lip 13 is formed upon the inner shoe 8, as also shown in Fig.

1, and the rope or cordat'ter leaving the draftcapstan 9 passes up around the curved block 12, and thence through a recess in the inner side of the bar 2 of the flier to the shoe S and down over the curved lip 13 of the same to the spool, the recess in the rod 2 of the flier extending almost from end to end of the same, so as to provide for the necessary longitudi- 7o nal traverse of the shoe 8 inlaying the rope or cord upon the spool. By this means the rope or cord is guided in its course from the draft-capstan to the spool without the use of any sheaves or other like moving parts'sub- 75 ject to Wear and requiringlubrication, the grooves or recesses in the inner side of the rod 2 of the flier-frame serving to prevent the rope kor cord from'being thrown outward by centrifugal force beyond the limits of said 8o frame, thus preventing the breaking ofv the rope or oord, which sometimes results When it is not thus confined. It will be noted that the shoe S does not project into the groove or recess of the bar 2. Hence there is no frictional retardation of the longitudinal movement of the shoe which is likely to attend the movement of any guiding device which does project into said groove, owing to the accumulation of lint or other foreign matters in the 9o groove in such quantity as to bear upon the sides of such projecting guide.

The spindle 3,Which supports the spool, has near its outer end a groove 14, and when the spindle is fully inserted this groove receives the notched lower end of a sliding plate 15, mounted on a bracket 16 at the end of the machine and capable of being secured in position by means of a thumb-nut 17, which is adapted to a threaded stud or bolt projecting roo as to permit the spool to be removed from the hier.

In order to prevent the accidental starting of the machine when a spool and the spindle have thus been removed, I connect to the sliding plate 15 a lever 21which is connected by a rod 22 to a catch-arm 23, suitably hung to the lower end of the machine and having a lug 24E for engagement with any available projecting part of the belt-shifting bar 20 when the latter is projected, so as to direct the belt onto the loose pulley 19, such engagement of the catch-arm 23 and belt-shifting bar 2O being effected by lifting the lever 2l in order to4 raise the plate 15 and free the spindle 3. The machine cannot be again started, therefore, until the plate 15 and lever 2l have been again intentionally depressed, and this movement will not take place until a fresh spool has been supplied to the hier and the spindle 3 has been again inserted to the point at which it can be locked by the depression of the plate 15, such movement withdrawing the lug of the catch-arm 23 from engagement with the belt-shifting bar 20, so as to permit the movement of the belt from the loose pulley onto the fast pulley.

Although I prefer the use of the lever 21 as a means of simultaneously operating the plate 15 and catch-arm 23, said catch-arm may be connected to the plate in any available manuel', so as to insure simultaneous operation of the two. I

In order to render unnecessary the lubrication of the bearing of the ring 5 in the traverse-frame et, I line with graphite each side of the recess formed in said frame for the reception of the ring, the graphite being preferably in the form of plugs 25, filling Openings formed in annular washers 2(5,which are suitably secured to the frame 4as, for instance, by screws 27, Fig. 8.

The washers 2G are preferably made in sections, as shown in Fig. 9, for convenience of handling, application, and removal.

Aing a shoe with curved lip for directing the In order to prevent the access of fine dirt, lint, or other foreign matters to the bearing of the ring 5 in the frame 4, I provide said ring with flan ges 2S, projecting laterally from each side of the same close to the inner face of the frame 4, so that foreign matters thrown outward by centrifugal force will strike these flanges and will thus be prevented from gaining access to the bearing.

Having thus described my invention, I wish it to be understood that I do not claim, broadly, the recessed bar of the flier-frame, as such recessed bars have hitherto been employed, but I claim as my invention and desire to secure by Letters Patent- 1. The combination in a winding-machine, of a spool-holder, the iiier having a bar with, recess in its inner side, and a shoe sliding along the inner side of said bar, and having a curved lip for directing the rope-or cord from the recessed bar of the ilier onto the spool, substantially as specied.

2. The combination in a winding-machine, of a spool-holder, a flier having a bar with recess on its inner side, a traverse-frame hav- 8o rope or cord toward the spool, and a bearingblock for receiving the cord or rope from the draft-capstan and directing it through the grooved bar' to the shoe, substantially as specified.

3. The combination of the spool-holder, the traverse-frame, the ring adapted to a groove or recess therein, the longitudinal bar of the flier recessed on the in ner side, a shoe secured to the traverse-ring and engaging said bar, said shoe having a curved or rounded lip, and a block secured to the flier-bar and serving to direct the rope or cord to the shoe on the traverse-ring, substantially as specified.

4. The combination of the recessed annular traverse-frame, the Hier-frame, and the ring rotating therewith and adapted tothe recess of the annular traverse-frame, said ring having lateral flanges extending completely around the same close to the inner face of the annular traverse-frame, substantially as specified.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.

ROBERT DAIVES.
